A delightful stir-fry dish combining tender beef slices with fresh vegetables and a tangy tomato-based sauce.
Mix the ginger, garlic, cornstarch, soy sauce, and egg white in a bowl.
Ensure the marinade is well combined to evenly coat the beef.
Add the sliced beef to the marinade and let it sit for 10 minutes.
Marinating the beef enhances its flavor and tenderness.
Heat oil in a skillet over medium-high heat and stir-fry the beef until browned. Remove and set aside.
Avoid overcrowding the skillet to ensure even cooking.
Add the green pepper, celery, and onion to the skillet and stir-fry until tender-crisp.
Stir constantly to prevent the vegetables from burning.
Mix the ketchup, sugar, cornstarch, and water in a small bowl.
Ensure the cornstarch is fully dissolved to avoid lumps.
Pour the sauce into the skillet and cook until it thickens.
Stir continuously to achieve a smooth sauce.
Return the beef to the skillet and add the tomatoes. Cook until heated through.
Add the tomatoes at the end to retain their freshness.
Serve the stir-fry over steamed rice and enjoy.
Garnish with chopped green onions or sesame seeds for added flavor.
